III. In patients entered on stage 1 of clinical trial whenever possible through pre-treatment biopsy and post-treatment surgical specimen, we will define target inhibition at tumor sites based on: AURKA autophosphorylation (AURKAThr288/AURKA), intra-tumoral drug levels, expression of p53-induced NOXA and PUMA expression, TPX2, (by IHC) and TUNEL as markers of apoptosis, cell cycle changes (mitotic index), proliferation (Ki-67), aneuploidy, and AKT phosphorylation.
